METHOD 0F OPERATING STEAM-VALVES 0F STEAM-PUMPS.

Specification of Letters Patent-No. 15,211, dated June .24, 1856.

To all whom t may concern.'

Be it known that I, REMY HENRY, of Melrose, in the county of Westchesterand State of New York, have invented a new and useful Improvement inSteam-Pumps; and I do hereby declare that the following is a full andexact description of the same, reference being had to the accompanyingdrawings and the letters of reference marked thereon.

The nature of my invention consists in giving motion to the steam valveof a steam pump by the alternate action of the pump and steam pistons,and in placing the pump and steam cylinders nearer together-for thepurpose of compactness and portability-than is practicable 4by any otherarrangement.

Figure l, in the annexed drawings is a horizontal sectionl of myimprovement-t-he valve being shown on the side of the steam cylinder,and Fig. 2 is a transverse section of a portion of the valve geardetached.

A is the pump cylinder, made with the valve attachments of anydescription that may be preferred; B, the pump piston; C, the steamcylinder; D, the steam piston; E, piston rod connecting the two pistons;F, a sleeve through which the piston rod works freely, but yetsufficiently tight at the end projecting into the steam cylinder toprevent the passage of steam past the piston rod into the pump cylinder.It is made tight on its exterior surface by being packed at thestuffing-boxes G, G on the interior heads of the two cylinders, and ismade as much longer than the distance from inside to inside of the twoheads as the movement required to be given to it to give the properthrown to the steam valve. It is moved by the pistons of the pump andsteam cylinders coming in contact with it as they alternately arrive atthe terminus of their stroke toward the inner heads of the twocylinders. H, steam chest and I steam valve to the steam cylinder, bothof ordinary construction-the steam being conveyed to the cylinder bypassing into the ports and passages past the ends of the valve, and fromit by passing to the exhaust port and passage through a cavity in thebody of the valve. J valve rod, attached at one end to the valve and atthe other end working in the guide K. L, a lever, working on a pin onthe bar M, by which the motion of the sleeve F is and at a properdistance from its centertoward the opposite end-to a pin on the valverod J, beyond which it extends sufficiently far to form a handle bywhich t-he valve can be operated by hand to start the pump. N, a strongspring, bearing in the direction of the sleeve F, connected to the pinon the sleeve F by the fork O. It effects the double purpose of givingthe valve a sudden opening as soon as the lever L and the fork O havebeen moved past a direct line by the piston striking the sleeve, and ofholding the valve in its proper position until the return stroke ismade.

As represented in the drawing, the sleeve has been moved, and the steamvalve thrown, by the pump piston, and the steam piston is moving towardthe inner head of the steam cylinder-on approaching the terminus of itsstroke, the sleeve, and by its connections, the valve, will be moved byit to make the return stroke.

While all the steam pumps at present in use require the pump and steamcylinders to be placed at least as far apart as the length of theirstroke, mine require only to be placed suiiiciently far apart to permitthe pin on the sleeve F to move back and forth a suflicient distance togive the proper throw to the steam valve, so that it will occupy lessspace and be more compact and portable.

I do not claim attaching the pistons of a steam cylinder and a pump toone rod and operating the pump by the direct connection, nor do I claimoperating the valve of a steam cylinder by the piston, but

What I claim as my invention and desire to secure by Letters Patent isl. Giving motion to the steam valve of a steam pump by the alternateaction of the steam and pump pistons, in the manner described.

2. The combination of the sleeve F, the lever L, the fork O, and thespring N to communicate the requisite movement to the steam valve.

REMY HENRY.
